To all whom t may concer/a.' j

Be it known that I, HARRY Y. NoRwooD, a citizen of the United States, residing at Rochester, in the, county of Monroe and State of New York, have (invented certain new and useful `Improvements vin VThermometerSupports; and I do hereby declare thev followingto be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference numerals marked thereon. e

` -This invention `relates to thermometer supports and, more particularly, to the varietyfcomprising vmeans for supporting a thermometer tube ijn adjustable relation with itscooperating scale, to facilitatethe .accurate assemblyl ofthe yparts during manufacture and for maintaining lthe accuracy thereof;

of theqinstrument yin use, "the chief object of the invention kbeing'gthe provision of a device ofthe above character having a simple, practical V,and economical formfoffconstruction convenient to adjust and of such an inconspicuous` nature as not to detract from the appearance .ofthe instrument.

Tothese and other ends the invention resides in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the` kclaims at'. the end of the specification.` j f In thel drawings: l

vFig. l is a' front elevationof a thermometer mounting embodying the presentinvention; j i f .A Fig.V 2 isa rear elevation of the same; i. Fig. 3 is an enlarged longitudinal section ,Fig 4 is an enlarged transverse section on the line A19-14?* .in Fig. 2;V

Fig. 5 is a fragmentary view similar to the upper portion of Fig. 2but with parts i detached;

, Fig. G is an enlarged sectional view on the line 61-6a in Fig. 2, and

Fig. 7 is an enlarged perspective view of an adjusting plate detached.

Similar reference numerals throughout the several views indicate the same parts.

The preferred embodiment of the invention herein disclosed by way of illustration isI in conjunction with a thermometer mounting of the type adapted, for example for attachrlri-ll.t liga window casing, com.-

prisingva main support 10 ypreferably in form of ametal plate of the character shown, the forward side of which has marked thereon or is .otherwise provided with a temperaturescale 11. Cooperating with the latter is an indicating tube 12 of the usual or any suitable variety constructed of glass with a longitudinal bore and a bulb portion 13 filled with mercury or other suitable temperature responsive fluid. The tube is preferably secured to the supporting means or plate 10 by metal straps 14 and 15 adjacent its top and bottom respectively. The strap 15 is fixed at its ends to the plate by small bolts 16 passed through the strap and the plate with securing nuts 17 thereon in therear ofthe plate. While this strap fits the tube closely its engagement therewith is suiiiciently light to permit of a longitudinal sliding movement of the tube on the main support under control of the `adjusting means hereafter described. f

\ yThe upper end of the thermometer tube is preferably formed with an angular or rearwardly turned end or finger 18, as well understood in the art, and `means are provided for cooperation with this tube end for adjusting the tube longitudinally relative to -the main supporting plate 10 and its scale. For this purpose platelO is'formed with a small opening 19 somewhat elongated longitudinallyV ofthe tube and in which the tube end 18`loosely enters with sufiicientplay longitudinally of the tube to allow the desired range of adjustment for the latter.

Preferably thetube endl projects somewhat rearwardly of plate 10 and enters an opening 20 in an adjusting means or, plate 21 sliding onthe rearsideof the main plate 10 as-shown. While plate 21 may obviously beA provided with shoulderfor other means projecting somewhat forwardly into opening 19 for engagement with the tube end, it is simpler and preferable to form plate 21 in thek flat shape shown and its opening 2O may besomewhat elongated laterally but is of such a width longitudinallyJ of the tube as to closely fit the tube end 18 in this direction, so that adjustment of the plate serves to accurately adjust the tube.

Means are provided for releasably clamping plate 21 in adjusted position on the rear of plate 10, comprising bolt and nut means carried by y,one of said plates and working in .a s101291r ,Slots ,in the @than 11.1 the PWS* ent instance, plate 10 carries tivo' small'bolts Q2 extending from the forivard side thereof on opposite sides of the tube rearwardly through openings in-v plate lO-in WhiclrtheV` boltsy are snugly'titted. f Rearivard-lyofplate ing suiticiently loose to permit of sliding adjustment ot the tube. Il so desired, this strap ,may however have such a length as to release the tube for sliding movement as described only when the adjusting means is unelamped and to ixedly clamp the tube on tliemain plate-when the `nuts @el ot the adjusting means are turned home 'lor securing plate 2liA In the manufacture ot` the instrument, the tubes are provided With a reference mark corresponding. to a knoivn temperature, aS Well'understood` in the art and the supporting'pla'tes provided With scales positioned thereon to correspond approximately ivith the indications ot the tubes. The tubes and supports may theube assembled in the manT ner described and the tube adjusted to register accurately uvith the scaleA by unclamping plate 21, adjusting the same to move and adjustV the tube and thenreelamping the part inpo'sitionjby ythe means described The 'invention thus provides a simple, ef-

fee-tive and' inexpensive fconstruetion for initially' 'ass'einbling' and subsequently *adjusting tubev and'its'niountingfand scale, The` :adjustmentV lmay be conveniently and quickly made'and the adjustingparts are; so constructed: and arranged fas to'be`1inconspicuous and. in fact practically invisible from" the front ot' the instrument-soVtlia't they do not' detract from the'Av appearance of the f latter. n

l claim as my invention:

Y l.' A thermometer comprising a support provided 4With a scale, an indicating tube cooperating with said scaley and mounted for adjustment longitudinally,on the support, a projection on the tube loosely entering an opening` in the support, a member mounted for adjustmentV on the support and iormed with-an opening in which said projection is engaged, and means releasably clamping said member to the support.

2. A thermometer comprising supporting meansprovidedwitha sale, an indicatingtube cooperating ivith said scale and mounted for adjustment longitudinally on said supporting means, said tube having an angular-ly turned end, an adjustable means mounted Aon said supportingmeans and formed with a recess in which said tube end is engaged, and a. bolt and nut carried by one ot' said means and Working in a slot in the other for releasably clamping said means together and Vsaid tube in adjusted position. y

2 3. A thermometer comprising a supportin plate provided With a scale, an indicat ing tube cooperating With said scale and mounted for adjustment longitudinally on the support, saidftube having 1a yrearwardly turned end loosely entering an openingin said' supporting plate,` an l adjustablefplate mounted on' the rear of said-.supporting plate and formed with a recess in' which said tube end is engaged, anda boltand nut carried by one ot' said plates and' Working in a slot in the other for releasably clamping said 'plates together vand said tube in adjusted position;
